Answer:
The plant would have to work 8.33 hours

Initial productivity:
100 parts were produced in 1 hour
Percentage increase in productivity = 20%
New productivity:
100 + (100 × 0.2) = 100 + 20 = 120
120 parts would be produced in 1 hour
Number of hours the plant would have to work to produce 1000 parts = 1000/120 = 8.33 hours

B. they involve the use of expert judgement do develop forecasts
Explanation:
A time series is a series of events that is spaced equally in time. It is a statistical technique used to identify a time based trend of events and them make forecast using data from the trend/time series.
Time series requires certain processes which include discovering of a pattern in the historical data, projection of the historical data into the future, assumption that the pattern will remain the same(constant) as the time goes by, etc.
In time series method, since historical data is the point of reference for making a forecast, no expert judgements is required to develop forecasts. This is because once the data of the series from the past has been taken and a trend/pattern has been identified, that becomes the basis for future forecasts.
